RAC 启动时发现 ORA-19808

ORA-19808: recovery destination parameter mismatch
(1)
[oracle@fps-ordb01 ~]$ oerr ora 19808
19808, 00000, "recovery destination parameter mismatch"
// *Cause: The value of parameters DB_RECOVERY_FILE_DEST and
// DB_RECOVERY_FILE_DEST_SIZE must be same in all instances.
// instance. All databases must have same recovery destination
// parameters.
// *Action: Check DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE
// values in all instances.
[oracle@fps-ordb01 ~]$
(2)分别在各自节点上检查参数 DB_RECOVERY_FILE_DEST
SQL> show parameter DB_RECOVERY_FILE_DEST
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string +FRADG
db_recovery_file_dest_size big integer 30G
真的发现db_recovery_file_dest_size 有一个试20G一个是30G
(3) 修改其中的一个节点为一致的大小
Alter system set db_recovery_file_dest_size = 30G scope=both;
(4) 重启服务!正常了
